Abstract

In this study, effects of cemented carbide coated with TiC+TiN, coated with TiC, uncoated and CBN on the machinability of AISI 410 martensitic stainless steel was investigated. In the experiments chip root morphology, cutting forces and surface roughness were determined. Experiments were done in the dry turning conditions. The cutting speed, feed rate and depth of cut were kept constant as, 60 m/min, 0.12 mm/rev and 1.2 mm respectively. Cemented carbide tool coated with TiC+TiN gave maximum cutting forces. Although CBN gave the minimum cutting forces, it was observed that it fractured in a shorter machining length. The optimum values of cutting force and surface roughness were obtained from cemented carbide coated with TiC.

Özet

Bu çalışmada, TiC+TiN, TiC kaplı sementit karbür, kaplamasız sementit karbür ve CBN kesici takımların AISI 410 martensitik paslanmaz çeliğin işlenebilirlik özelliklerine etkileri araştırılmıştır. Bu amaçla, talaş kökü morfolojisi, kesme kuvvetleri ve yüzey pürüzlüğü incelenmiştir. İşlenebilirlik deneyleri kuru tornalama ortamında gerçekleştirilmiştir. Deneylerde 60 m/dak kesme hızı, 0.12 mm/dev ilerleme hızı ve 1.2 mm talaş derinliği sabit tutulmuştur. TiC+TiN kaplı sementit karbür takım en yüksek kesme kuvveti değerlerini vermiştir. CBN takım en düşük kesme kuvvetlerini vermesine karşın, kısa işleme mesafelerinde takımda kırılmalar meydana gelmiştir. Kesme kuvvetleri ve yüzey pürüzlülüğü bakımından optimum değerler TiC kaplı sementit karbür takım ile talaş kaldırma işleminde elde edilmiştir.
